This immediately suggests that Alnico 8 will have a larger magnetic field compared to Alnico 5 when magnets are short compared to their pole area. Alnico alloys can be magnetised to produce strong magnetic fields and has a high coercivity (resistance to demagnetization), thus making strong permanent magnets. Excellent temperature stability, high residual induction and relatively high energies characterize Alnico materials, composed primarily… Alnico permanent magnets form a family of alloys whose major constituents are iron, aluminum, nickel and cobalt, though other elements (e.g., copper and titanium) may be included in minor amounts. Alnico magnets are part of the permanent magnet family, and relatively high in magnetic strength. Like the Alnico 2, it has more treble, scooped mids and a tighter low end, but not perhaps as brassy as an Alnico 2. Grades of Alnico vary in cobalt content, which ranges from zero (Alnico 3) to 40% (Alnico 8). Alnico magnets can de-magnetize from hard knocks or strong currents, some strength may be lost just over time but as to if always and how much I've heard contradictory things. Their Mechanical Strength is greater than Neodymium or Ferrites. 0.5kg - 1kg. • Alnico bar magnets may be ground to size but not by conventional machining. Alnico 3 has the lowest strength of the Alnico magnets with zero cobalt content. With the ALnico 4’s flatter “EQ”, the guitar’s true colour and character really shine through – this is where Alnico 4’s can sometimes sound bland. Unoriented magnets have random 'grain' and a more complex and varied magnetic field. While alnico magnets have largely been replaced by stronger rare-earth magnets they are still commonly used in the manufacturing of sensors, guitar pickups, loudspeakers and many other everyday household objects. Not a huge difference. 99 ($1.75/Item) This magnet is the 2nd lowest strength magnet in the Alnico range which results in fantastic vintage dynamics and flavour.
